An Audiom map of the main Smith-Kettlewell building at 2318 Fillmore St., San Francisco has been created by Brandon Biggs. This is an audio-visual map that allows users to explore a detailed map of the building with or without vision. The map runs in any browser and is available to anyone who visits the building.
For individuals who are blind or have low vision, tactile maps provide essential spatial information but are limited in the amount of data they can convey. Digitally augmented tactile maps enhance these capabilities with audio feedback, thereby combining the tactile feedback provided by the map with an audio description of the touched elements. In this context, we explore an embodied interaction paradigm to augment tactile maps with conversational interaction based on Large Language Models, thus enabling users to obtain answers to arbitrary questions regarding the map. We analyze the type of…
People with visual impairments increasingly rely on camera-enabled smartphone apps for tasks like photography, navigation, and text recognition. Despite the growing use of these applications, precise camera aiming remains a significant challenge. This project explores the impact of virtual reality (VR) exploration in the context of learning to use a camera-based app. So far we have studied this approach in the context of training a visually impaired person to use walk-light detector app at traffic intersections.
Age-related macular degeneration (AMD) is the most common cause of vision loss in the developed world. Central visual field loss due to diseases such as AMD is a large and growing problem. It is also associated with higher risk of falls and, therefore injury. Although much has been done to understand visual limitations associated with this condition, one of its most dangerous and poorly understood outcomes is the increase in the risk of falls, which can be debilitating and even deadly, especially in the age group most affected by AMD. The exact reasons for the increased fall risk are unknown…
The project aims to develop a rapid, objective vision screening tool for identifying amblyopia in preschool children using abnormal binocular
It has been a mystery as to what level of cortical hierarchy is suppressed in visual processing from the amblyopic eye and how neural representations change when increasing contrast or paying attention to the amblyopic eye. In this project, we will adapt a standard EEG binocular rivalry paradigm, which modulates stimuli at different frequencies in each eye and incorporates a behavioral measure of perceptual eye dominance. We will simultaneously measure neural activity along the cortical hierarchy and perceptual eye dominance under 3 conditions: equal contrasts in the two eyes, perceptually…
A discussion group for parents of children and parents and older children with Cerebral Visual Impairment (CVI) supported by clinicians, researchers and teachers of the visually impaired. Next Meeting: Monday January 27th 2025 at 12pm to 1.30pm Pacific Time
Vergence to disparity targets in the central visual field is impaired in individuals with amblyopia and strabismus.
The goal of the “Empowering Data Vision: A Data Science Course for Blind Individuals” program is to help people with visual impairments acquire advanced skills related to STEM subjects and careers.
This project is focused on investigating sources of error and potential improvement methodologies for head-free eye tracking, particularly in individuals with known oculomotor deficits
